3 SHEETSSHEET 3 To allwhomt'tmay cancer 1 r Be it known that I,HARRY'H.'SCHRQYE1,

' a citizen of the United. States, and a resident of the city ofChicago, in the county of 5 (look and State of Illinois, have inventedcertain new and useful Improvements in Metallic Car-Diaphragms; and I dohereby declare that the following is a full, clear,

and exact description of the same, reference being had to theaccompanying drawings,

and to the numerals of reference marked thereon, which form a part ofthis specifi'cw' tion.

With the almost widespread introduction of steel cars for passengertraffic on railroads, attempts have been made to construct metalvestibule diaphragms for attachment on the ends of the car which may beconnected to one another to afiord a sealed weatherproof passage betweenthe cars which are coupled together. Such a diaphragm must not onlyafiord a weatherproof passage between the cars, but. as well he capableof adjustment due to the severe conditions of usage imposed thereon,owing to relative movement taking place between the coupled cars onwhich diaphragms of this type are mounted. I a a It is an objecttherefore of this inventlon to construct a metallic car diaphragmwherein the sides and top arching over the platform extension of the carare constructed of metal, the elements thereof being so designed andassociatedwith one another as to permit the necessary ad usting move=inents to take place when relative movements between the cars occur suchas in traveling over an uneven roadbed, negotiating curves, or duringswitching operations.

It is also an object of this invention to construct a metallic cardiaphragm comprising metal walls and top members integrally connected toone another and having the face plates sealingly and adjustably mountedthereon, and adapted to telescope within top and side wall membersassociated with the car to compensate for variations in move mentbetween the coupled cars on which diaphragms constructed according tothe principles of my invention are mounted and connected to one another.

It is also an object. of this invention to construct a metallic cardiaphragm wherein the side and top walls of the diaphragm are 55arranged to telescope with stationary re Specification or hettersPatent. Pafigmtlsfl F H 11% w a li ation filed a i-u 10,1918. Serial he.cares.

1 ceivingmembers-mounted rigidly on the cat g andprovidedwithsealingmeans and with the face plates of the diaphragmadjustably mounted on the outer end-of said metallic top and side wallsfor relative movement with respect thereto.

It is furthermore an important ob'ect ofthis invention to construct ametal ic. car diaphragm wherein integral top and side walls are deformedat the1r forward edges to slldably and adjustably interfit with meansmounted on a face plate forming a part of the diaphragm topermitadjusting movements of the face plate to take place andfurthermore co-acting with sealing means to afford a telescopicconnection between the side and top walls of the diaphragm and the mainbod of the car to permit extension and contraction of the metallicdiaphragm.

It is finally an object of this invention to construct an improved tvpeof metallic car diaphragm capable of extension and adjustment tocompensate for inequalities and variations of alinement between coupledcars acting eiliciently to afiord a sealing connection for passagebetween the cars.

The invention (in a preferred form) is illustrated in the drawings andhereinafter more fully described.

As shown in the drawings:

The end of a car body is denoted as whole by the reference numeral 1,and secured rigidly thereto at the upper end thereof is a horizontalfiatmetallic receivin compartment comprising a top wall 2, an a bottom wall3, with the outer margins of tho top wall 2, turned upwardly at rightangles, as denoted by the reference numeral 4, and secured in anysuitable manner to the body portion of the car. As clearly shown Y wall8, and an outer wall 9, integrally conturned outwardly and rigidlysecured to nected to one another and with the upper margins of the innerwall 8, turned inwardly and rigidly secured to the bottom wall 3, of theupper horizontal compartment, and the upper margin of each of the outerwalls 9,

said bottom wall '3, said bottom wall 3, havinga slot therein, asclearly shown 1n Flg. 3, at the junction of the upright walls 8 and 9,therewith. Angle iron braces 10, are secured to each of the outer walls9, and to an upright I-beam frame member 11, forming a part of the carbody. Inserted into the 0 en end of the compartment afforded by t ewalls 8 and 9, are thin metallic strips 12 and 13, having belting orother sealing material 14, thereon.

The telescoping sections of the diaphragm adapted to slide within theside wall and top compartments described, consist of side wall plates15, adjustably connected as hereinafter described and shown in Figs. 3,4, and 5, to a top wall plate 16. For this purpose, the upper margins ofthe respective side walls 15, are turned inwardly at a right angle, andsecured on the under surface of the side margins of the top wall 16, aredownwardly bent plates 18, to afford recesses to receive slidablytherein the inwardly turned margins 17 of the side walls, and a strip ofsealing material 19, is secured upon the top surface of each of theinwardly turned ortions of the side wall plates sealing against theunder surface of the top wall plate 16. "An adjustable connection isprovided for both the side wall plates 15, and the top wall plate 16, attheir forward or outer end at the connection thereof to a face plate 20.For this purpose, the forward margins of each of the side wall plates15, are bent outwardly as denoted by the reference numeral 21, and shownin detail in. Fi 6, and beaded over, as denoted by the re erence numeral22. Secured upon the rear face of the face plate 20, is ametallicstrip-23, with one margin thereof bent outwardly and spaced away fromthe surface of the face plate to aflorda recess for the reception of.the beaded portion 22, of said side 7 wall'plate,so that "the same fitssnugly and sealingly therein and yet said face plate is capable-ofangular ad ustment with respect thereto. The top wall plate 16, at itsforward edge, is provided with an upturned margin 24, as shown in Figs.4 and 7 which abuts against a wear plate 25, secured upon the face ofthe vestibule face plate and en- -I have shown a slightly differentconstruction from that shown in Fig. 6, wherein in place of the beadedportion of the shape designated by the reference numeral 22, in Fig. 6,is shown a rounded almost circular bead 28, formed on the bent margin21, of the side wall plate.

The operation is as follows:

The side walls 15, and top wall 16, which telescope within the narrowside wall and top compartments secured rigidly on the car body, aresealingly and to some extent adjustably held therein and are capable ofadjusting movements, so that the weaving effect which is imposed upon adiaphragm in use is readily taken care of without noise or wear upon theparts. As bufling and draft stresses take place between coupled cars,the respective diaphragm sections on the cars are contractedor expanded,as the case may be, the telescoping elements sliding one within theother. Due to the adjustable connection between the top wall and theside walls of the telescoping sections of the diaphragm, it is p ssiblefor one side wall to be extended or contracted a greater amount than theother, as for instance when a pair of coupled cars are traveling on'acurved track or in switching, the top wall swinging laterallyduring'such movement within the top wall compartment therefor, which isconsiderably wider than the top wall 16, itself to permit such swingingmovement to take place. The face plate 20, is allowed to assume angledpositions with respect to the telescoping sections of the vestibulediaphragm due to the yieldable connection between the top and side wallsand said face plate, and furthermore said face plate is capable ofsliding vertically to a certain extent to prevent strain being imposedupon the parts due to the weaving effect imposed upon the connecteddiaphragm sections of cars coupled to one another. The strips of seal ngmaterlal shown consist of cotton belting, serving to effect a sealingconnecmembers.

aacaoaa the diaphragm is comparatively easy-to manufacture and assemble,and is simple in operation, and damage to any one of the parts thereofmay be easily repaired by replacement.
